Core(3X) Core(3X) NAME Core - The Core widget class SYNOPSIS #include <Xm/Xm.h> DESCRIPTION Core is the Xt Intrinsic base class for windowed widgets. The Object and RectObj classes provide support for windowless widgets. Classes All widgets are built from Core. The class pointer is widgetClass. The class name is Core. New Resources The following table defines a set of widget resources used by the pro- grammer to specify data. The programmer can also set the resource val- ues for the inherited classes to set attributes for this widget. To reference a resource by name or by class in a .Xdefaults file, remove the XmN or XmC prefix and use the remaining letters. To specify one of the defined values for a resource in a .Xdefaults file, remove the Xm prefix and use the remaining letters (in either lowercase or uppercase, but include any underscores between words). The codes in the access column indicate if the given resource can be set at creation time (C), set by using XtSetValues (S), retrieved by using XtGetValues (G), or is not applicable (N/A).

The accelerator table can then be installed on some destination widget. Specifies whether the immediate parent of the widget receives input events. Use the function XtSetSensitive to change the argument to preserve data integrity (see XmNsensitive below). For shells, the default is copied from the parent's XmNancestorSensitive resource if there is a parent; otherwise, it is True. For other widgets, the default is the bitwise AND of the parent's XmNsensitive and Xm- NancestorSensitive resources. Specifies the background color for the widget. Specifies a pixmap for tiling the background. The first tile is placed at the upper left-hand corner of the widget's window. Specifies the color of the border in a pixel value. Specifies a pixmap to be used for tiling the border. The first tile is placed at the upper left-hand corner of the border. Specifies the width of the border that surrounds the widget's window on all four sides. The width is specified in pixels. A width of zero means that no border shows. Specifies the colormap that is used for conversions to the type Pixel for this widget instance. When changed, previously generated pixel values are not affected, but newly generated values are in the new colormap. For shells without parents, the default is the de- fault colormap of the widget's screen. Otherwise, the default is copied from the parent. Specifies the number of bits that can be used for each pixel in the widget's window. Applications should not change or set the value of this resource as it is set by the Xt Intrinsics when the widget is created. For shells without parents, the default is the default depth of the wid- get's screen. Otherwise, the default is copied from the parent. Specifies a list of callbacks that is called when the widget is destroyed. Specifies the inside height (excluding the border) of the widget's window. Specifies whether or not resources are reference counted. If the value is True when the widget is cre- ated, the resources referenced by the widget are not reference counted, regardless of how the resource type converter is regis- tered. An application that expects to destroy the widget and wants to have resources deallocated should specify a value of False. The default is True, implying an assumption that the wid- get will not be destroyed during the life of the application. If set to True it maps the widget (makes it visible) as soon as it is both realized and managed. If set to False, the client is responsible for mapping and unmapping the widget. If the value is changed from True to False after the widget has been realized and managed, the widget is unmapped. Specifies the screen on which a widget instance resides. It is read only. When the Toolkit is initialized, the top-level widget obtains its default value from the default screen of the display. Otherwise, the de- fault is copied from the parent. Determines whether a widget receives input events. If a widget is sensitive, the Xt Intrin- sics' Event Manager dispatches to the widget all keyboard, mouse button, motion, window enter/leave, and focus events. Insensi- tive widgets do not receive these events. Use the function XtSetSensitive to change the sensitivity argument. Using XtSet- Sensitive ensures that if a parent widget has XmNsensitive set to False, the ancestor-sensitive flag of all its children is ap- propriately set. Points to a translations list. A translations list is a list of events and actions that are to be performed when the events occur. Specifies the inside width (excluding the border) of the widget's window. Specifies the x-coordinate of the upper left outside corner of the widget's window. The value is relative to the upper left inside corner of the parent window. Specifies the y-coordinate of the upper left outside corner of the widget's window. The value is relative to the up- per left inside corner of the parent window. Translations There are no translations for Core. SEE ALSO Object(3X), RectObj(3X) Core(3X)
